• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. ((thien van) OR (thi van)) cac xuc ((van thanh) OR (ban thanh)) di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. ((thien van) or (thi van)) cac xuc ((van thanh) OR (ban thanh)) di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. ((thien van) or (thi van)) cac xuc ((van thanh) OR (ban thanh)) di cua tre*.
